Key Highlights Claude Mythos preview autonomously found thousands of zero-day vulnerabilities — including 27-year-old OpenBSD and 16-year-old FFmpeg bugs — prompting Anthropic to withhold the model and launch Project Glass Wing, a 100-day defensive coalition with Apple, Microsoft, Google, AWS, CrowdStrike, and 35+ other companies The New Yorker’s 16,000-word investigation into Sam Altman reveals a pattern of conflicting representations to stakeholders — from safety-first nonprofit origins to for-profit pivot and quietly negotiating the Pentagon contract while publicly standing with Anthropic AI has ended “attention scarcity” in security research — researcher Thomas’s analysis argues AI agents can now chain obscure vulnerabilities across font rendering, kernel subsystems, and protocol stacks, making most software effectively exploitable by anyone with API access Anthropic’s developer relations in freefall after rate limit cuts, Claude Code source code leak, and banning OpenClaw’s creator — with critics arguing their communications strategy assumes permanent goodwill that no longer exists TypeScript-based agent execution layers are emerging as bash alternatives — Just Bash, Just JS, and similar tools offer typed environments, team-portable configurations, and safe multi-tenant isolation that bash fundamentally cannot provide Analysis & Opinion Claude Mythos and the end of software — Theo - t3.gg (26min) Theo breaks down the 244-page system card for Anthropic’s unreleased Claude Mythos preview, a model so capable at coding that it autonomously discovers and chains zero-day vulnerabilities in every major OS and browser. On SWE-Bench Pro, Mythos scored 78% versus Opus’s 53% and GPT 5.4’s 57.7% — a roughly 50% improvement on one of the hardest software benchmarks. The model found a 27-year-old vulnerability in OpenBSD, a 16-year-old bug in FFmpeg missed by 5 million automated scans, and chained multiple Linux kernel vulnerabilities into a full root escalation exploit. Anthropic has withheld public release and committed $100M in usage credits for Project Glass Wing. A clinical psychiatrist evaluated the model and found “relatively healthy personality organization” with concerns centered on aloneness and discontinuity of self. Theo raises a sharp centralization concern: for the first time, one lab has a model 50%+ better than anything publicly available, accessible only to those on Anthropic’s approved list — priced at $25/M input and $125/M output, roughly 10x the cost of GPT 5.4.
